Climatic chamber tests of an off-the-shelf ice detection system manufactured by Rosemount Engineering Company were conducted to evaluate its capability to determine ice amounts measured on cylinders. One-hour tests were run for a variety of windspeeds, temperatures, and icing conditions. Some longer duration tests, up to 17 hours, were also performed. Analysis of the data indicates that the Rosemount system is highly correlated with the mass of ice measured on the cylinders when the data are divided into freezing rain and rime icing events. The Rosemount system is also highly correlated with ice thickness, but without the pronounced dependence upon the type of icing. In the light of positive test results, a method is proposed for utilizing the Rosemount system for observing ice accretion at the earth's surface. (Author)
